INVENTOR ATTORNEY I JOSEF MILLER, OF BROOKLYN, NEW YORK.

GAS-LAMP.

Specification of Letters Patent.

Patented Dec. 22, 1908.

Application filed July 30, 1908. Serial No. 446,179.

T o all whom it may concern.'

Be it known that 1, JOSEF MILLER, a subject of the Czar of Russia, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful imrovements in Gas-Lamps, of which the folowing is a specification.

This invention relates to gas lamps of the kind usually employed for illuminating` stores, halls and the like and the invention resides in certain details of construction set forth in the following specification and claims and illustrated in the annexed drawing, in which:

Figure l is a side elevation partly in section of a lamp embodying this invention, Fig. 2 is a section along line x :z: Fig. 1, Fig. 3 shows a pilot light device, Fig. 4 shows a modificatlon.

Referring to the above drawing the letter a (Fig. 1) indicates a gas supply pipe to which can be secured the upper shade t. Branching from the pipe a are two gas pipes c c each of which at its upper portion and directly beneath supply pipe a is bent to a semi-circle. Each of these pipes c and c are further bent or curved outwardly at their upper portions. This last named or upper curve or bend of pipes c and c serves to present handle portions when screwing or attaching the lamp in place and also to ex? tend the pipes away from heat caused by the burning of the gas. These curves also serve to present an ornamental appearance.

The pipes c and c extend downwardly to a union e provided with valve f. This union e supports the burner proper g upon which is mounted a glass chimney h. Above this chimney and extending partly over the same is an intensifier i, provided with the usual top or cap k. instead of having the draft holes or openings of this intensifier at or near its center as was usual heretofore l locate or provide such draft openings at the upper part of the intensifier as seen at m which arrangement allows the mantle to better retain heat and give more light.

The intensier or tube is held in position between the two tubes by means of two brackets. Of these two brackets the upper one shown at n is composed of two duplicate members and provided with the customary semi-circular middle portion which fits around the tubeor intensifier 'i and of radially dis osed arms which fit around the tubes c anti c. This bracket is also provided with bolts or screws o to clamp the two members together. The lower bracket p also has the semi-circular middle portion sitting around the tube i with radially disposed arms which clasp the tubes c and c and screws or bolts to clamp the two sections or members together. The members or sections of this lower bracket are suitably extended and bent to lit the inner side of the shade holding band or crown 1 and screws or bolts s applied to these extensions secure the crown in place.

At t are shown screwsin the crown 11 which screws hold the shade u in place.

As thus seen the bracket p supports the crown r which in turn supports or carries the shade u by screws other than those which clamp the crown to the bracket. This arrangement allows removal of the shade u without disturbing or loosening the crown r from bracket p.

At o (Figs. 1 and 3) is shown a pilot light device which is brazed, screwed or otherwise secured t0 pipe c. This pilot light has a nipple which extends through the pipe c and is provided with a screw valve w for regulating or controlling the flow of gas into and through elbow tube 2. The screw valve w is located at the side away from the flame so that when setting such screw the Jlingers of the person setting said screw do not come into contact with either the chimney h or intensifier fi. This arrangement also gives firmer attachment of the pilot light device.

The elbow tube 2 of the pilot light device is rotary and extends into a slit above the bottom of the intensifier so that the said tube never lies on the glass chimney but is located above the top of said chimney. When the tube 2 is in the position shown in Fig. 1 it prevents vertical as well as rotary movement of the intensifier in the brackets.

In the modification shown in Fig. 4 the intensiiier is made to terminate above the chimney 7L in which case the intensifier need not be slitted for reception of pilot light 'v but this pilot can be located between the intensiiier and chimney. The upper bracket can be done away with and the intensifier in Fig. 4 is shown suspended from the gas pipes below the shade b.

In Fig. 4 the intensifier is not shown fastened to the bracket but passes loosely through the same.

Now what I claim is:

1. A gas lamp comprising tubes with a burner and chimney, an intensiiier, a nipple secured into and through one of the tubes from the side facing the intensifier, a screw valve for the nipple extended intoV the tube from the side opposite or away from the intensifier, and a pilot jet tube extended from the nipple t0 above the chimney.

2. A gas lamp comprising tubes with burner and chimney, an intensifier, a nipple secured into and through one of the tubes from the side facing the intensiiier, a screw valve for the nipple extended into the tube from the side opposite or away from the in-` tensifier, and a pilot jet tube extended from the nipple to above the chimney, said intensiiier having a slit located entirely above the bottoni of the intensifier to allow the pilot tube to enter the same above the top of the chimney.

3. A gas lamp comprising tubes with a burner, a chimney, and an intensifier above 2o the chimneywithoutlet at its top, the tubes being located at each side of the intensifier and being curved or directed outwardly and extended away from the intensier at the upper portions opposite the intensifier outlet 25 my hand in the presence of two subscribing 30 witnesses.
